Study the table and find the value for R. 
To find the value of R (the profit/loss percentage for Article 1), we need to follow these steps:
| Articles | Cost Price | Marked Price | Discount | Selling Price | Profit/Loss % |
|---|---|---|---|---|---|
| 1 | 12600 | +20% | 10% | W | R |
- Calculate the Marked Price: \(\text{Marked Price} = \text{Cost Price} + 20\% \text{ of Cost Price}\)
Substitute the values given:
\(\text{Marked Price} = 12600 + \frac{20}{100} \times 12600 = 12600 + 2520 = 15120\)
- Calculate the Selling Price after Discount: \(\text{Selling Price} = \text{Marked Price} - 10\% \text{ of Marked Price}\)
\(\text{Selling Price} = 15120 - \frac{10}{100} \times 15120 = 15120 - 1512 = 13608\)
- Calculate the Profit/Loss Percentage: \(\text{Profit/Loss Percentage} = \frac{\text{Selling Price} - \text{Cost Price}}{\text{Cost Price}} \times 100 \%\)
Substitute the values:
\(\text{Profit/Loss Percentage} = \frac{13608 - 12600}{12600} \times 100 = \frac{1008}{12600} \times 100 \approx 8\%\)
Thus, the value of R is 8%.
